The present invention concerns basic others. More particularly, it relates to compounds having the formula in which Ph is a 1,2-phenylene radical, Ar is a monocyclic carbocyclic aryl group substituted by tertiary aminolower valkyl-oxy, in which tertiary amino is separated from oxy by at least two carbon atoms, R is hydrogen, an aliphatic radical, a carbocyclic aryl radical, a carbocyclic aryl-aliphatic radical, a heterocyclic aryl radical or a heterocyclic aryl aliphatic radical, the group of the formula -(C,,H stands for an unbranched alkylene radical having from three to five carbon atoms and carrying the groups Ar and R, salts, N-oxides, salts of N-oxides or quaternary ammonium compounds thereof, as well as procedure for the preparation of such compounds.

The compounds of the present invention may be prepared according to methods known per se, for example, by converting in a compound having the formula:

in which Ph, R, and the group of the formula have the previously given meaning, and Ar is a monocyclic carbocyclic aryl radical substituted by a hydroxyl group, or preferably a metal compound thereof, the hydroxyl group of the radical Ar into a tertiary amino-lower alkyl-oxy group, and, if desired, converting a resulting salt into the free compound or into another salt, and/or, if desired, converting a resulting compound into an N- oxide or a quaternary ammonium compound there, and/ or, if desired, converting a resulting compound or an N-oxide into a salt thereof, and/or, if desired, converting a quaternary ammonium compound into another quaternary ammonium compound, and/or, if desired, separating a mixture of isomers into the single isomers.

The conversion of the hydroxyl group attached to the radical Ar into the desired tertiary amino-lower alkyloxy group is carried out according to known procedures. For example, the starting material having the phenolic hydroxyl group attached to the group Ar may be converted into a metal salt, particularly an alkali metal, e.g. lithium, sodium, potassium and the like, salt. Formation of the metal compound may be achieved, for example, by reacting the starting material with a metal compoundforming reagent, such as an alkali metal hydride 0r amide, e.g. lithium hydride, sodium hydride, sodamide, potassium amide and the like, or any other suitable reagent, such as an alkali metal lower alkanolate, e.g. lithium, sodium or potassium methanolate, ethanolate, tertiary butanolate and the like, or an alkali metal compound of a hydrocarbon, eg. butyl lithium, phenyl lithium, phenyl sodium and the like. The preparation of the metal compounds is carried out in the presence of an inert solvent, e.g. hexane, benzene, toluene, xylene, diethyl ether, p-dioxane, tetrahydrofuran, diethyleneglycol dimethylether, N,N-dimethylformamide and the like, or any other suitable solvent, such as a lower alkanol, e.g. methanol, ethanol and the like.

The starting material, particularly the metal compound thereof, is then reacted with a reactive ester of a tertiary amino-lower alkanol, particularly a compound of the formula Am(C I-I )X, in which Am and the group of the formula (C H have the previously given meaning, and X stands for a reactive esterified hydroxyl group. The latter is above all a hydroxyl group esterified with a strong mineral acid, such as hyd-rohalic acid, e.g. hydrochloric, hydrobromic acid; therefore, the group X represents primarily halogeno, e.g. chloro, bromo and the like. It may also be a hydroxyl group esterified with a strong organic sulfonic acid, such as a lower alkane sulfonic acid, e.g. methane sulfonic, ethane sulfonic acid and the like, or a monocyclic carbocyclic aryl-sulfonic acid, e.g. p-toluene sulfonic acid and the like; thus, the group X may also stand for lower alkyl-sulfonyloxy, e.g. methylsulfonyloxy, ethylsulfonyloxy and the like, or monocyclic carbocyclic aryl-sulfonyloxy, e.g. p-tolylsulfonyloxy and the like. The preferred reactive esters of a tertiary amino-lower alkanol are those having the formula Am(C I-l )Hal, in which Am, and the group of the formula (C,,,H have the previously given meaning, and Hal represents halogeno, particularly chloro.

The reaction of the starting material, particularly a metal compound thereof, with the reactive ester of a tertiary amino-lower alkanol is carried out in a suitable diluent, for example, in the solvent used for the preparation of a metal compound, if necessary, While cooling or at an elevated temperature, and/ or, in the atmosphere of an inert gas, e.g. nitrogen.

The starting material used in the above reaction is known or may be prepared according to known methods.

The compounds of this invention may also be prepared, for example, by reacting a compound having the formula:

1 11 (birth-2 in which Ph, Rand the group of the formula have the previously given meaning, and Ar" is a monocyclic carbocyclic aryl radical substituted by a reactive esterified hydroxy-lower alkyl-oxy group, in which the re active esterified hydroxy portion is separated from oxy by at least two carbon atoms, with a secondary amine, and, if desired, carrying out the optional steps.

A reactive esterified hydroxy-lower alkyl-oxy group is particularly a group of the formula O-(C H )-X, in which X and the group of the formula --(C,,,H have the previously given meaning; the reactive esterified group X is primarily a group Hal representing halogeno, particularly chloro, as well as a suitable organic sulfonyloxy group. The reaction of the starting material with the secondary amine, having preferably the formula H+Ani,

in which ,Am has the above given meaning, is carried out in such manner, that an excess of the amine or of any other suitable base is present to neutralize the generated acid; if necessary, the reaction mixture may be diluted with, a suitable inert solvent. 7

The starting material used in the above reaction is prepared according to known methods, for example, by reacting the alkali metal compound of the starting material of the previous procedure with a halogeno-lower alkanol, and converting in a resultingicompound, in which the monocyclic carbocyclic aryl group has a hydroxy-lower alkyloxy substituent, the hydroxyl group of such substituent into an esterified hydroxyl group, for example,'by

treatment with a thionyl halide, eg. thionyl chloride and the like, or with an organic sulfonic acid halide, e.g. chloride and the like, in the presence of a suitable base, e.g. pyridine and the like.

The compounds ofthis invention may also be prepared by converting in a compound of the formula which Ph, Ar and R have the previously given meaning, and the group of the formula -(C H is an unbranched alkenylene radical having from three to five carbon atoms and carrying the groups Ar and R, thealkenylene' radical of the formula (C H into the desired alkylene radical ofthe formula having from three to five carbon atoms and carrying the groupsAr and R, and, if desired, carryingout the optional steps.

The conversion of the alkenylene radical into an alkylene radical is carried out according to methods known per se, for example, by treatment with an alkali metal, eg sodium and the like, in the presence of a lower alkanol, with metal amalgam in the presence of a hydrogen donor, e.g. sodium amalgam in the presence of moist diethyl ether, catalytically activated hydrogen, such as bydrogen in the presence of a palladium catalyst and the like, or any other suitable method.

The starting materials used in the above reaction may be prepared, for example, by converting in a compound of the formula I 11 (bani-i) in which Ph, Ar, R and the group of the formula have the previously given meaning, or preferably a metal salt thereof, the hydroxyl group of the radical Ar into a tertiary amino-lower alkyl-oxy group; this reaction 'is carried out as previously shown, for example, by reacting the metal salt with a reactive ester of a tertiary aminolower' alkanol. ing a group Ar substituted by hydroxyl may be prepared, for example, by reacting a benzocycloalkanone com- The above unsaturatedcompounds hay-- pound, inwhich the cycloalkane, portion carries thesub- The compounds of this invention may also be prepared,

For example, a mixture of diastereoisomers may be separated into the individual racemic compounds on the basis of physico-chemical differences, such as solubility, for example, by fractional crystallization and the like. Racernates may be resolved into the optically active dand l-forms according to known resolution procedures, for example, by forming a salt of the free racemic base with one of the optically active forms of an acid containing an asymmetric carbon atom. Especially useful as optically active forms of salt-forming acids having an asymmetric carbon atom are D-tartaric (l-tartaric) acid and L-tartaric (d-tartaric) acid, as well as the optically active forms of malic, mandelic, 10- camphor sulfonic, quinic acid and the like. From a resulting salt, the free and optically active base may be obtained according to the method described above, and a free and optically active base may be converted into its acid" addition salt, N-oxide, salt of an N-oxide or quaternary ammonium compound according to the procedures described above.

The invention also comprises any modification of the process wherein a compound formed as an intermediate at any stage of the process, is used as starting material and the remaining step(s) of the process is(are) carried out, as well as any new intermediates.

In the process of this invention such starting materials are preferably used which leadto final products mentioned in the beginning as preferred embodiments of the invention.
